Introduction

As resource demands and pressure increases so to do the requirements of both management and information needs. Outlined below are the key issues facing the region as determined by the State / Territory water management agency.

What is the estimated demand for surface water in Endeavour River?

How was this assessment undertaken in the Endeavour River Surface Water Management Area?

Development Potential:

This SWMA is in an isolated region of the state with little existing development other than grazing and some forestry activities. Due to this isolation there is a low probability of any new development unless an emerging industry is identified. Therefore, there is little potential for Water Development in this SWMA. A further impediment to potential development is the existence of the declared World Heritage Wet Tropics rainforest area which occupies approximately 20% of this SWMA. This same 20% has also been allocated as a timber reserve - a conflicting land use that is unlikely to be fully developed due to the restrictions imposed by the World Heritage listing. Additionally, this SWMA drains into the Great Barrier Reef Marine Park World Heritage Area.

Management goals and objectives:

No Detailed Management Plans have yet been developed.

See QLD Water Resources Assessment 2000 Report and Water Resources Assessment 2000 Technical Report for comment on methods and assumptions.

Assessment of Monitoring

Efficacy of the network:

The Department of Natural Resources (Queensland) carries out extensive monitoring of the States water resources. Flows are continuously monitored and data is kept in the HYDSYS database. Water quality is continuously monitored at selected gauges and is also sampled when hydrographers visit the gauges. All quality data is stored in the HYDSYS database. This monitoring network is reviewed periodically.

All water use in the State is licensed. Use on unregulated streams and from overland flow is not measured. Use from regulated streams is metered with the meters being read at regular intervals. Data on water allocations made by the Department of Natural Resources (Queensland) is held in the WERD database. Data on water allocated by an Order in Council or a Government Act is not held in a centralised database.

All Referable Storages are licensed.

The streams in this SWMA are unregulated. This SWMA is in an isolated area with little development or potential development unless an emerging industry is found. There is currently little need for data in this area.

No data on water use is available. There are currently two gauging stations in operation recording height and discharge including one that records water quality.

Data management requirements:

See the main database for additional comments on Current and Desired Management responses.

Protective management:

Any major developments, which require the use of water or are liable to effect water quality within Queensland, are required to carry out an Environmental Impact Assessment. This is required for both developed and undeveloped catchments.

Options for monitoring:

NA

See QLD Water Resources Assessment 2000 Technical Report for an assessment of monitoring

Data Availability, Gaps and Recommendations

Data Availability:

There is one stream gauge currently operating within the SWMA

Water quality has been monitored at three sites in the SWMA.

All regulated users are metered and water use is measured at regular intervals.

Information and records for the gauges are held in the HYDSYS database.

Records of allocations for all licenced users are kept in the WERD database. Regulated users have volumetric allocations and unregulated users have an irrigated area allocation. Unregulated water users are not metered and there is no record of water use. Allocations granted under an Order in Council for special users such as Local Authorities or under Government Acts are not held in a centralised database.

Current Gaps and Recommendations:

Data Gaps: No measurement of unregulated water use. No measurement of water harvesting use. No detailed environmental flow assessment of key sites in the SWMA. Recommendations:

Future Gaps:

Water resource system models are the main management decision tools which will need to be linked in the future to improve economic, financial, social and environmental response models. Good data and information are fundamental to the accuracy and validity of these tools. Some of the needs and gaps associated with this data and information are discussed below:

There is little knowledge of the land use impacts on stream flow over a period of time.

There are limited records of the quantity of water extracted from the main stream and overland flow by water harvesting.

A database is required for all water allocations other than those already contained in the WERD database. This would include all allocations made by Government Act and Order in Council.

No information is available for unregulated water use as these users do not have meters. Much of the water harvesting in the State is also unmetered unless it is on a regulated stream.

See QLD Water Resources Assessment 2000 Technical Report for a review of data availability,gaps and recommendations.
